In a simple data communication system, terminals and other remote I/O devices are linked with one or more central processors to receive input data and capture output information. Connecting equipment and software, sometimes referred to as interface elements, are used to bridge the different physical and operating environments that exist between I/O devices and central processors.

Some possible DDP configurations are:

Star DDP Network: A central host computer(s) communicates and controls a second level of satellite or node processors. These nodes in turn communicate with I/O terminals.
